檢索HTTPResponse/HTTPRequest狀態碼iPhone SDK？

Question

我需要檢查和評估我的iPhone應用程序中的HTTP狀態代碼。我有一個的NSURLRequest對象和NSURLConnection的是成功地（我認爲）連接到站點：

// create the request 
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"] 
         cachePolicy:NSURLRequestUseProtocolCachePolicy 
        timeoutInterval:60.0]; 
// create the connection with the request 
// and start loading the data 
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 
if (theConnection) { 
    // Create the NSMutableData that will hold 
    // the received data 
    // receivedData is declared as a method instance elsewhere 
    receivedData=[[NSMutableData data] retain]; 
} else { 
    // inform the user that the download could not be made 
} 

我得到這個代碼在這裏：http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html

但事實並非如此（只要我能看到）說任何關於訪問HTTP狀態代碼。

任何人都有任何想法如何建立一個網站的連接，然後檢查該連接的HTTP狀態代碼？

在此先感謝！

Answer 1

這是我要做的事：

#pragma mark - 
    #pragma mark NSURLConnection Delegate Methods 
    - (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response { 
     NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response; 
     int responseStatusCode = [httpResponse statusCode]; 
    } 

但我使用一個異步NSURLConnection的，所以這可能幫不了你。但我希望它無論如何！
